Report on the Geology & Gold Fields of Otago

Tokomairiro

Tokomairiro.

This specimen was forwarded by Capt. Hutton from Tokomairiro. It is an excellent ore. On aualysis it shows of—
Susquioxide of iron 79.5 per cent.
Water 14 0 per cent.
Earthy matter 6.5 per cent.
This is equal to 55.75 per cent. of metallic iron, and in such a state of combination and purity as to be very easily reduced. It will, if found in large quantity be a very valuable ore of iron, and should not be neglected.
